How about a small introduction of yourself to the readers of Supermoto Central?

[Hartl Racing] I'm Matthias Hartl, owner of from Putzbrunn/Munich in Germany.

How did you get into supermoto and what do you find so great about it?

[Hartl Racing] The first bike I bought was 1995 a Suzuki RG80 Gamma. In 1996 I got two older Honda MTX80 - my first bike project was born! I drive many years with different bikes, mostly 1000ccm Racebikes. After a harder crash with my bike, my girlfriend told me not to drive much longer such bikes. So... a few years ago I started with supermoto...


When and how did the idea for this project originated? What was your inspiration?

[Hartl Racing] This is the bike of a customer and good friend of my. We do this project this winter.


 What’s was the base for your project?

[Hartl Racing] A perfect looking bike, with massive horsepower. We had about 75hp on this bike. It's really great!

Can you tell us in short how the build went? Did you have any big problems or did it all went smooth?

[Hartl Racing] One problem was the 5,5" rear wheel. 5,5" it's a little bit wide, so we modded the swing arm. Now we had no problems with the chain. Other problem is the double brake disk... it's a little bit tricky with two brake disks.


What do you use your bike for? Do you ride it on the street or just take it to the track once in a while?

[Hartl Racing] this bike is only for the track.

Is this your first supermoto project or did you also build other supermoto bikes?

[Hartl Racing] no, this is not my first. I have many bikes build.




Do you have any plans for another supermoto project in the future?

[Hartl Racing] well... I don't know. I like caferacer's. When I had a good idea and a lot of time, I will do a project like this.


Have you got any tips or advice for people that want to start a project like this?

[Hartl Racing] Don't buy those cheap and worthless junk from ebay... you will regret it.
